Ethyl methyl carbonateis an organic compound ine kemikari formula C5H8O3, inozivikanwawo seEMC.Imvura isina ruvara, yakajeka, uye isingachinjiki ine muchetura wakaderera uye kusagadzikana.EMC inowanzoshandiswa seyakagadzirwa muminda senge zvinonyungudutsa, machira, mapurasitiki, resin, zvinonhuwira, uye mishonga.Inogona zvakare kushandiswa kugadzirira mamwe organic komisheni, senge polycarbonate.Mukugadzirwa kwemaindasitiri, kugadzirwa kweEMC kunowanzo tora ester exchange reaction kana carbonation esterification reaction.

Zita rechigadzirwa: Ethyl methyl carbonate

CAS:623-53-0

Molecular formula:C4H8O3

EINECS:433-480-9

Nzvimbo yekushandiswa kweEMC yakadzika ndeye lithium-ion bhatiri electrolyte, inova imwe yezvinhu zvina zvikuru zvemabhatiri e-lithium-ion uye inodaidzwa zvakajeka se "ropa" remabhatiri.

EMC yakakamurwa kuita mapoka maviri zvichienderana nekuchena: indasitiri giredhi methyl ethyl carbonate (99.9%) uye bhatiri giredhi EMC (99.99% kana kupfuura).Industrial giredhi EMC inonyanya kushandiswa mumaindasitiri organic synthesis uye zvinonyungudutsa;Iyo bhatiri giredhi EMC maitiro inoda yakakwirira zvinodiwa uye inonyanya kushandiswa se solvent ye lithium-ion bhatiri electrolytes.Nekuda kweiyo diki steric chipinganidzo uye asymmetry muchimiro, inogona kubatsira mukuwedzera kunyungudika kwelithium ions, kuvandudza capacitance density uye kuchaja kwebhatiri, uye yave imwe yezvishanu zvinonyungudutsa zve lithium-ion bhatiri electrolytes.

Nzvimbo yekushandiswa kweEMC yakadzika ndeye lithium-ion bhatiri electrolyte, inova imwe yezvinhu zvina zvikuru zvemabhatiri e-lithium-ion uye inodaidzwa zvakajeka se "ropa" remabhatiri.Mumakore achangopfuura, nekukurumidza kukurumidza kweiyo nyowani simba mota indasitiri, yeChina lithium-ion bhatiri electrolyte indasitiri yakapinda munguva yekukurumidza kusimudzira.Huwandu hwenzvimbo yemagetsi emagetsi hwakawedzera zvakanyanya, uye kutsiva kunze kwenyika kwave kuwanikwa, zvichifambisa kukurumidza kukura kwekudiwa kweEMC mumusika weChina.Zvinoenderana ne "2023-2027 China EMC Indasitiri Yekutsvagisa uye Development Prospects Forecast Report" yakaburitswa neXinsijie Indasitiri Research Center, muna 2021, kudiwa kweEMC muChina kwaive 139500 matani, gore negore kuwedzera kwe94.7% .

Musika weEMCyakaratidza kukura kwakadzikama mumakore mashoma apfuura.Izvi zvinonyanya kukonzerwa nekushandiswa kwakapararira kweEMC mumashandisirwo akasiyana siyana emaindasitiri, senge zvinonyungudutsa, machira, mapurasitiki, resin, zvinonhuwira, uye mishonga.Pamusoro pezvo, nekuvandudzwa kwehupfumi hwenyika pamwe nekuvandudzwa kwemararamiro evanhu, kudiwa kweEMC kuri kuwedzerawo zvishoma nezvishoma.

Parizvino, matunhu makuru evatengi emusika weEMC anosanganisira Asia Pacific dunhu, Europe, uye North America.Dunhu reAsia Pacific ndiro dunhu guru revatengi vemethyl ethyl carbonate musika, neChina, Japan, neSouth Korea vari ivo vanonyanya kugadzira uye vatengi veEMC.Musika weEMC muEurope neNorth America uri kukurawo zvishoma nezvishoma, Germany, United Kingdom, United States, neCanada vari ivo vatengi vakuru veEMC.

Mune ramangwana, kukura kwemusika weEMC kuchapesvedzerwa nekusimudzira hupfumi hwenyika uye maindasitiri.Nekusimuka kwemisika iri kusimukira uye kuenderera mberi kwetekinoroji, kudiwa kweEMC mumusika kucharamba kuchikura.Pamusoro pezvo, kuchengetedzwa kwezvakatipoteredza uye kusimudzira kwakasimba kuchavawo maitiro akakosha mumusika weEMC, kusimudzira kugadzirwa uye kushandiswa kweEMC kuti ive nehushamwari uye inogadzikana.
